Researchers may be one step closer to a Viagra for women, given the results of a British study released Tuesday.

Sexual side-effects of antidepressants may improve with Viagra use.

Attempts to treat female sexual dysfunction with Pfizer'serectile dysfunction drug Viagra have for the most part failed, but a new prototype from the company offers hope for a female-specific treatment for those with female sexual arousal disorder, FSAD.
The drug, which the researchers tested on rabbits, acts by increasing blood flow specifically to the genitalia, enhancing and extending the duration of arousal.
The drug would not help all types of female sexual arousal disorder, however, as blood flow is only one of many reasons that women experience sexual dysfunction.
"This is the closest thing out there to Viagra for women," says Sheryl Kingsberg, chief of the division of behavioral medicine at University Hospitals Case Medical Center in Cleveland, "but the problem is that a Viagra-like effect will not solve the majority of sexual dysfunction cases in women.
"In contrast to men in whom erections have played a huge role in sexual health, for women arousal is not the key problem, desire is," she said.
